Caution - potential fire hazard

First review but it was dangerous. I thought this PSU was working properly for a few months but was having weird issues with weird freezes attributed to the software. Accidentally moving things, one day I touched the power cord and heard the electrical hiss of a weak connection/arc. Took it apart and on the back of the power button I saw the bottom trunk connectors were blacked out. With the connection removed carbon deposits could be seen behind the arc, this was done with a fairly tight connector on the pin. That surge of current in this power supply is super unsafe. I decided to solder the two wires together, bypassing the power button, and (of course) no more hissing, and my instability/crashing issues stopped. I don't know enough about how most power supplies are assembled, but soldering at the switch, while an extra step and cost, would eliminate that point of failure, I don't know if this is an isolated case, but I wouldn't do it yourself would conveniently run one of them without those points soldered to the back of the switch. Image of the burned connector housing for reference.

Pros
  • AI Silent Heat Dissipation System: AI temperature control technology controls heat dissipation to keep noise level ≀28dB. Compared to other products, the large 140mm UtechSmart RGB PSU fan adopts hydraulic bearing technology that provides up to 7% more air intake, up to 3% noise reduction, and synchronizes RGB with the fan. Double ball bearings ensure a fan life of over 50,000 hours.
Cons
  • Hard to say
